SPECIFICATION forming part of Letters Patent o. 617,790, dated January 17, 1899.

Application tiled November 80, 1896. Serial No. 613,855.' (No model.)

To UZZZ whom t may concern;

Be it known that I, HoRATIo L. WILLARD, a citizen of the United States, residing at Somerville, in J[he county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Draft- Tubes for Soda-Fountains or other Like Apparatus, of which the following is a speciiication, reference being had therein to the accompanying drawing, which is a vertical central section of a draft-tube embodying my invention.

My invention relates to that class of drafttubes through which a coarse or fine stream of iiuid under pressure is dispensed.

The object of my invention is to produce a draft-tube of economical construction; and my invention consists in the constructional features pointed out-in the claim.

In the drawing, a is the main supply-pipe, which discharges in chamber b in the casting c, having in this instance an ornamental chambered extension CZ. A coarse-stream tube Z is mounted in the extension CZ and extends well up into chamber Z). Its upper end is closed by a suitable plug, in which the fine-stream tube Z6 is mounted. This tube is within the coarse-stream tube Z5 and has an opening at its lower end. The upper end of tube Z is formed with a valve-controlled.

a spring Z4 to any suitable support such, for example, asis afforded in this instance by the upper part of tube Z6. The Valves m and m project from the plates Z2 and Z3, respectively,

toward and against the outer ends of the ports m3 and m4, respectively, and are held in place to close the ports by the springs Z4. The plates extend beyond the inner end of the tube Z, and a cam c, having a lobe 7a2, is mounted between the plates. This cam is carried by the usual handle, and by rocking the cam so as to bring lobe k2 against plate Z2 Valve'm is pushed away from the port 'm3 and a iine stream dispensed. By rocking cam lo so as to bring lobe k2 against plate Z3 valve 'm2 is pushed away from port m4, so that a coarse stream is dispensed.

What I claim isl In a draft-tube, the combination of a coarsestreaml tube and a fine-stream tube With a chambered casing having an inlet-port ports leading from said coarse-stream tube, and ine-stream tube to the said chambered casing; the Valves m and m2 covering said ports, the springs Z4, Z4t attached to the arms Z2 and Z3 to which said valves are secured and the cam Zo provided with the lobe 7a2, substantially as described.

In testimony whereof I have signed my name to this speciiication, in the presence of two subscribing witnesses, on this 28th day of November, A. D. 1896.
